preparation example Construction

[0067] An exemplary preparation method includes: adding 10% NaOH solution to the lignosulfonate solution, adjusting the pH of the solution, adding epichlorohydrin (ECH), and performing a synthesis reaction at 60-80°C. After the reaction is finished, take out the reaction product and distill under reduced pressure to remove unreacted epichlorohydrin (ECH), wash the precipitate with deionized water until it is neutral, and dry it in vacuum to obtain the product.

[0068] Preferably, the trace element compound includes but not limited to one or more of sulfates of iron, zinc, manganese, molybdenum, copper, magnesium, titanium or potassium;

[0069] The surfactant is preferably a quaternary ammonium salt cationic surfactant, including but not limited to alkyl trimethyl ammonium salt type, dialkyl dimethyl ammonium salt type, alkyl dimethyl benzyl ammonium salt type, pyridinium salt type , alkylisoquinolinium salt type or benzyl ammonium chloride salt type, preferably alkyltrimethy...

Abstract

The invention discloses a fertilizer special for peanut and a preparation method thereof and relates to the technical field of compound fertilizers. The fertilizer special for peanut comprises a firstfertilizer core, a first encapsulating layer, a second fertilizer layer, a yoghurt powder layer and a second encapsulating layer which are encapsulated layer by layer from inner to outer; the first fertilizer core contains urea, diammonium phosphate, ammonium chloride and ammonium bicarbonate; the first encapsulating layer contains acylate beta-cyclodextrin and konjaku flour; the second fertilizer layer contains urea, diammonium phosphate, lime nitrogen, ammonium bicarbonate, humic acid and additive; the additive include seaweed meal, grondverbeteraar, amino calcium and dicyandiamide; the second encapsulating layer contains lignin gel, inulin, urea, oxalic acid, microelement compound and surfactant. The fertilizer disclosed by the invention has balanced nutritional ingredients, is moderate in phosphorus and potassium elements and is capable of effectively reducing the wastage rate of fertilizer, increasing the utilization efficiency of fertilizer, boosting the quick and healthy growthof peanut and achieving high yield of peanut per unit and full and plump peanut seeds.

Description

technical field [0001] The invention relates to the technical field of compound fertilizers, in particular to a special fertilizer for peanuts and a preparation method thereof. Background technique [0002] Peanut is a kind of nut with abundant output and wide consumption in our country. It is the main source of plant protein for human beings, and it is also an important raw material for oil and food. The demand for peanuts is constantly increasing, therefore, it is necessary to increase the yield of peanuts. [0003] Peanut special fertilizer is an effective way to ensure peanut production, but the current fertilizer utilization rate is low. According to statistics, the utilization rate of nitrogen in fertilizers in my country is about 30-35%, phosphorus is 10-25%, and potassium is 35-50%. , far below the level of developed countries in the world, which not only wastes resources, but also causes environmental pollution. Slow-release fertilizers have the characteristics of ...
